Maybe Pat is ribbing me over my contention that Swordfish are generally not worth looking for. I stand my ground!

I'm with Keith on this one, as I have been for years. Nothing against Swordfish of course, but I don't think the risk-reward ratio is very good. I'm open to change if someone can tell a paper-and-pencil solver how to look for them efficiently.

There was a recent exception, perhaps on one of Dan's puzzles, where there were two Swordfish, but I think that puzzle had a grid that was less busy than usual, making them relatively easy to spot.
